If you can’t obtain a particular book, periodical, or media item from your library, use interlibrary loan to borrow it from another library. You can fill out a request form in person, but most libraries allow you to request materials through the library catalog, too. You may even be able to check the status of your request or renew interlibrary loan materials in the same way. To learn how to use interlibrary loan, consult your library’s Web site or ask a librarian.
